Patti was among the people in Ten Forward when Data, Deanna Troi, and Miles O'Brien possessed by Ux-Mal criminals stunned several crewmembers and took hostages. She was not among the hostages later and possibly escaped from Ten Forward. (TNG: "Power Play")
Patti was played by recurring background actress Denise Lynne Roberts who received no credit for her appearances.
She was called "female crewperson" in the script for "Transfigurations" and named on screen.
